Here's why:
* Saturated Solution: A solution where the solvent (usually a liquid) has dissolved the maximum amount of solute (the substance being dissolved) at a specific temperature. Adding more solute won't dissolve.
* Supersaturated Solution: A solution that contains more dissolved solute than a saturated solution at the same temperature. This is an unstable state, and any disturbance can cause the excess solute to crystallize out of solution.
Think of it like this: Imagine a glass of iced tea. You add sugar until it's no longer dissolving. This is a saturated solution. If you somehow manage to keep adding sugar and get it all to dissolve (maybe through careful heating), you've created a supersaturated solution.
